Further, contact LP3 is configured in the side of contact LP2, and contact LP5 is configured in the side of contact LP6, and contact LP4 is configured between contact LP3 and contact LP5, and contact LP7 is configured in contact LP6 side, and contact LP8 is configured in contact LP9 side.
Pay close attention to the contact that voltage is provided from camera main-body 100 to interchangeable lens 200, the arrangement of contact is as follows.These 12 contacts of contact LP1～LP12 circular-arc alignment arrangements in maintaining part 202.Contact LP12 is configured in one end of this circular-arc arrangement, and contact LP1 is configured in the other end.Contact LP11 is configured in the side of contact LP12, and contact LP2 is configured in the side of contact LP1.And contact LP3～LP6 is in the circular-arc alignment arrangements in the side of contact LP2, contact LP7～LP10 is in the circular-arc alignment arrangements in contact LP11 side.
That is, in the contact of circular-arc arrangement, provide contact LP1, the LP12 of supply voltage in two ends configuration, configuration of side is therein as contact LP2, the LP11 of the ground terminal corresponding with each supply voltage.And the contact LP3～LP10 of other communication systems is configured between these two contact LP2, the LP11 as ground terminal.
In the contact LP3～LP10 of the contact as communication system (communication system contact) and the contact of power-supply system, provide between the contact LP1 and LP12 of supply voltage (above-mentioned operation voltage, driving voltage), be configured as contact (ground contact) LP2 and the LP11 of its ground terminal, why forming is like this to be suppressed to Min. for the impact that the contact (signal wire) on communication system causes by the contact of power-supply system (signal wire).
Provide the signal wire (comprising the signal wire of LP1, LP12) of supply voltage according to the load change in the supply target of supply voltage, produce larger change in voltage.This larger change in voltage causes harmful effect to the signal wire of communication system sometimes.In order to suppress this harmful effect, in the present embodiment, by and the contact (ground contact LP2 and LP11) used of the ground terminal of power supply contact (LP1, LP12) comparison with voltage vary stable be configured between communication system contact LP3～LP10 and power supply contact LP1, LP12.
Be connected to the contact LP3～LP6 and the contact LP7～LP10 configuration adjacent one another are that is connected to lens side the 2nd Department of Communication Force 218 of lens side the 1st Department of Communication Force 217, but contact LP9, the LP10 of contact LP3, the LP4 of lens side the 1st Department of Communication Force 217, LP5 and lens side the 2nd Department of Communication Force 218, form the side that is not configured in the contact being connected with the Department of Communication Force (217 or 218) of differ from one another (another)., at the position of the contact near connecting from the Department of Communication Force of different (another), centralized configuration contact LP6, LP7 and LP8.This be for, as described below, transmit and the nonsynchronous signal of clock signal (compared with the signal of synchronizeing with clock signal, with it, change less signal, for example state variation under the unit interval is the signal of 1kHz～number kHz left and right) to contact LP6, LP7 and LP8.Generally, variation under the unit interval of clock signal, the signal of synchronizeing with it is fiercer, and for several MHz left and right, (as an example, clock signal is 8MHz, the data-signal (also depending on data volume) of synchronizeing with it is 4MHz), easily become noise source.Therefore,, for the impact that this terminal is caused communication is Min., preferably configure away from each other from the contact that is connected to difference (another) Department of Communication Force.Therefore adopt in the present embodiment following joint configuration: make to transmit and the contact group (contact LP6, LP7, LP8) of the nonsynchronous signal of clock signal, between the contact group (contact LP3, LP4, LP5) of the lens side interior transmission clock signal of the 1st Department of Communication Force 217 and the signal of synchronizeing with it and the lens side interior transmission clock signal of the 2nd Department of Communication Force 218 and and the contact group (contact LP9, LP10) of its synchronous signal between.
